Title: Process for preparing a powder of water-insoluble polymer which can be redispersed in a liquid phase and process for preparing a dispersion of the powdered polymer
IPC: A61K9/16
Filed: 1988-04-01
Granted: 1993-01-20
Abstract: A water-insoluble polymer powder that can be redispersed in a liquid phase is obtained by proceeding as follows: first prepare a two-phase liquid-liquid system from a concentrated aqueous solution of a solute and a solution of the polymer in an organic solvent which is at least partially miscible with water, and then add water to it until all of the organic solvent has diffused into the aqueous phase. The polymer microparticles are then washed and dried. When resuspended in water, they result in a pseudo-latex.

Abstract: A controlled impedance connector assembly comprised of a mutually engageable plug and receptacle for termination of coaxial cable leads in a manner which enables rapid attachment to and detachment from a user board of a very large number of signal leads while ensuring an acceptable level of controlled impedance from the coaxial cable to the user board. The receptacle includes a backup plate and a plurality of metallized grounding segments fixed to the backup plate and having a plurality of spaced parallel terminal receiving bores therein extending between opposed surfaces. An insulation plate is fixed to each grounding segment and overlies one of the surfaces. A plurality of pin contacts are fixed to the insulation plate such that a head member extends into an associated terminal receiving bore and an oppositely directed tail member is adapted for termination at available circuitry. The plug includes a frame mounting a plurality of dielectric segments each having a plurality of parallel spaced terminal receiving bores extending between a front and rear face. The dielectric segments are floatingly mounted for movement within defined limits in directions transverse to the axes of the terminal receiving bores. A terminal mounted to the extremity of each of a plurality of coaxial leads is removably received in an associated terminal receiving bore with a locking spring being utilized to prevent inadvertent removal of a terminal but subject to purposeful manipulation to enable removal of the terminal. Each bore of the grounding block receives and retains a barrel spring for frictionally holding a terminal in place engaged with the lead member of a pin contact. In another embodiment, a plurality of side by side dielectric strips replace the single insulative plate and permit soldered connections between the pin contacts and stripline cable at a location remote from the receptacle. When the heat employed in soldering the connections has dissipated, the strips are then attached to a one piece grounding block thereby avoiding harm of other components by reason of the heat. The dielectric strips are shaped to enable termination of a high density of stripline cables without causing undue interference between neighboring cables.

Abstract: La présente invention concerne un système de purification d'eau qui crée un écosystème intégré à petite échelle d'eau de mer ou d'eau douce, cet écosystème étant particulièrement utile en tant qu'aquarium de laboratoire, de bureau, d'école ou domestique. En fonctionnement, l'eau provenant du réservoir (56) de l'aquarium est acheminée vers un écran épurateur d'algues (10) ou une surface équivalente de croissance d'algues placées dans un réceptacle mobile, sensiblement plat, placé horizontalement et en forme de plateau (21). Une tourbe d'algues (14) comprenant de préférence une colonie dense de microalgues se trouve sur l'écran (10). Au fur et à mesure que le réceptacle (21) se remplit d'eau, le centre de gravité du réceptacle (21) se déplace sur l'axe (25) des pivots (24) sur lesquels est monté le réceptacle (21). A ce moment, le réceptacle (21) rempli d'eau tourne sur ses pivots (24) et on obtient un effet de contre-foulement désiré au travers de l'épurateur (10) par l'eau qui sort. Le reflux ou contre-foulement, l'énergie lumineuse fournie par des lampes (18, 32) placées au-dessus du réceptacle (21) et la photosynthèse des algues favorisent l'échange métabolique entre les cellules et l'eau ambiante pour éliminer le dioxyde de carbone et d'autres substances polluantes.

Abstract: The invention relates to an adapter for testing integrated circuits (8) mounted on a film, with the aid of a test device containing a load board (2) with spring-loaded needle contacts (10). The test device itself contains a load board of complex construction on which spring-loaded contact needles are located in a pattern which is advantageous for the production of this board. Since the grid dimensions of the chip connections (1) (spider) are much smaller than the grid dimensions of the spring-loaded contact needles (10) of the load board (2), it is not possible to test such chips mounted on film without changing the grid dimension of the load board (2). To eliminate this disadvantage, the invention provides that an intermediate circuit board (4) with conductor tracks fanning out from the centre is arranged to adapt the chips with the load board (2) of the test device, the grid pattern in the centre corresponding to the grid pattern of the chip terminals (1) and the grid pattern at the periphery corresponding to the grid pattern of the load board and the chip terminals (2) being pressed against fixed needle contact pins located at the circuit boards of the centre by means of test stamps (7). <IMAGE>
